It applies the most advanced digital storage technology to live store spectrogram all the time and can playback, spectrogram freeze; it is convenient for doctors to conventionally monitor the spectrogram and review medical records.
Clinical conventional examination is rapid, convenient and easy to operate. Under online condition, it can be adjusted plus, blood flow direction, sampling depth, ultrasonic strength, zero line, surveyor's staff and scanning rate as you like.

Examination parameters are full. Under online condition, it can display blood flow two direction's period of contraction peak flow rate, diastasis flow rate, average flow rate, PI index, RI index and S/D proportion any time.
Advanced operation flow setup, doctors can set operation flow according to their own examination procedures.
There are every age group's sex normal parameters stored in the computer, which are examined by domestic famous TCD experts, under online situation examination, if some parameter over normal range, it will warn by color.

Rich offline post-processing function. It can re-modify and re-store the blood flow spectrums that are already stored, such as re-examine blood flow rate by hand movement, adjust blood flow direction, zero line and plus and so on. It has functions such as word and chart marking to spectrum, spectrum playback, delete useless spectrums.
Medical records data management function is great. It can be inquired rapidly. Large-volume hard disc can store tens of thousands spectrum data can it can use floppy disc to store.
It has a unique TCD diagnosis report mode. Any spectrum chart print, call examination technology data and analysis parameters can be completely printed.
